Edgecore Networks compatible ET6401-LR4 Description

EdgeOptic's Edgecore Networks ET6401-LR4 compatible is an Edgecore-coded 40GBASE-LR4 version of the EdgeOptic 40G-QSFP-10 multi-vendor QSFP+ transceiver. It carries ET6401-LR4 coding so Edgecore open networking switches read it as a native 40G LR4 optic for 40 Gigabit Ethernet links over single-mode fiber.

The module follows IEEE 802.3ba Clause 87 for 40GBASE-LR4, with four CWDM lanes at 1271, 1291, 1311 and 1331 nm multiplexed onto one duplex LC connection. It reaches 10 km over standard G.652 single-mode fiber and carries a 6.6 dB optical link budget. A DFB laser drives each lane between −6 dBm and +3 dBm, the PIN receiver holds −12.6 dBm sensitivity per lane with a +3 dBm overload point, and the module operates across the 0 to 70 °C commercial range. DOM reports temperature, supply voltage, laser bias, and optical power in real time.

ET6401-LR4 is the Edgecore accessory code for the ET6401 series 40G data center and open networking switches, which run SONiC and OcNOS as Ethernet-only platforms. To confirm the switch models and software releases that qualify a 40GBASE-LR4 QSFP+, check the Edgecore transceiver compatibility documentation for the platform in use.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For volume pricing or deployment questions, contact our sales team.

Frequently Asked Questions

Does the ET6401-LR4 compatible work in Edgecore switches running SONiC or OcNOS?

Yes. EdgeOptic codes the module to match Edgecore ET6401-LR4 EEPROM, so SONiC and OcNOS identify it as a standard 40GBASE-LR4 QSFP+ without extra driver configuration. Open networking stacks read transceiver identity differently across switch models, so confirm the optic against the Edgecore transceiver compatibility list for the specific ET6401 model and NOS release. For a deployment check, contact our sales team.
